By taking advantage of parallel data processing and transmission techniques, the data access rate of a redundant array of independent disks (RAID) level 5 can be boosted significantly. A data distribution and aggregation unit is utilized to distribute a data stream into a plurality of data sub-streams based on the primitive data access block of storage devices as a processing unit of data writing, or to aggregate a plurality of data sub-streams to form a data stream based on the primitive data access block of storage devices as a processing unit of data reading. An exclusive OR operation unit capable of parallel data processing is introduced for performing data processing on the plurality of data sub-streams simultaneously. The data transmission of each data sub-stream is controlled individually by one of a plurality of transmission controllers.

When booting a host, a host peripheral system sends a boot code to the host for controlling the booting operation of the host via a serial transmission line, and loads an external program code into the host. After setting up a transmission mechanism through executing the external program code, the host can forward a write command to the host peripheral system for writing the data provided by the external program code to the command identification sector of the non-volatile memory of the host peripheral system, and the host peripheral system is capable of identifying the data as a command and executes functional operations corresponding to the command. After finishing the functional operations, the host peripheral system forwards a finish signal to the host, and the host is able to send a read command for fetching the data signal generated in the functional operations.
